Nice! Great to hear you are listening to them! They are still very high on my list of bands I currently listen to the most.
Many were down on R&H at the time because of how it was a mix of live and studio tracks, instead of being a normal studio album. But, really, most of the studio tracks are aces (except for one or maybe two). "All I Want Is You" will never be topped, "Hawkmoon 269" is definitely a killer tune, and I simply adore "Van Diemen's Land." The other three hits from it are good, too. And we cannot forget about the underrated gem that is "Heartland."
In regards to AB, I am surprised you don't like "One" or "Until the End of the World," which seem to be the most similar to U2 stuff you would already be familiar with. I can see why "The Fly" would be somewhat of a shock to the system. That aside,
Achtung Baby is far and away my favorite U2 CD, and "Ultraviolet (Light My Way)" is a phenomenal song that must be heard by anyone interested in the band.
Given what you like so far, War is definitely a good place to go next. It is mostly really good (except for "The Refugee" and the god-awful "Red Light"), and has several U2 standards you will recognize, as well as some hidden gems like "Surrender" and "Drowning Man."
Anyway, keep us apprised of your progress!
